將 combobox 上的選定項目連接到 pyqt5 中的一行

Question

當在 combobox 中按下項目時，我想調用 csv 並檢索在 combobox 中單擊項目時匹配的行

class Ui_Dialog(object):
 def setupUi(self, Dialog):
    sales=pd.read_csv ("C:/Users/DELL/Desktop/Info/Topholdings/csv/Master_table.csv")
    sales_article = sales ["Company"] .dropna()
    sales_list = sales_article.values.tolist()
    self.Fundwise = QtWidgets.QComboBox(Dialog)
    self.Fundwise.setGeometry(QtCore.QRect(308, 141, 141, 61))
    self.Fundwise.setObjectName("sales_list")
    self.Fundwise.addItems(arr_list)

In the above code I call the csv file and select the first column as list which is displayed in the combobox,but when the user clicks one of the items in the combobox how to call the selected strings row

Answer 1

def setupUi(self, Dialog):
     #....
     self.Fundwise.activated.connect(self._set_fundwise)

def _set_fundwise(self):
    _data = self.Fundwise.currentData()
    if _data:
       #call selected strings
